Résumé :

This article presents a real-time runnable permanent-magnet-assisted synchronous reluctance machine model that accounts for spatial harmonics and magnetic saturation and cross-saturation. It is based on offline evaluations of a finite-element model that represents the geometry of the machine with great accuracy, over a grid of current and rotor position values. The collected current - flux-linkage data are then fitted with one polynomial function per rotor position. The coefficients of the polynomials are then stored and used for time-based simulations. The model is first validated statically by analysing the regression error over the training dataset. Secondly, a dynamic simulation is performed to compare it with a lookup-table-based model in realistic conditions.
